ARGENTINA DEVICE FOR FLUSHING W`ATER-CLOSET PANS Application led March 28, 1929.' Serial No. 350,688.

The present invention has reference to improvements in devices for flushing watercloset pans. Heretofore water-closet pans were ushed by pulling a chain, or moving l5 a lever or other hand operated means, while according to the present invention the flushing mechanism is operated by the foot.

.The advantages of this invention consist, firstly, in added cleanliness, as the invention avoids contact of the hand with the ilushing device, and secondly, in easy and reliable operation,vand also in duration, and in improved appearance. The improved apparatus may be used on any kind of water-closet, Whether flushed by lever, chain or button.

The device in accordance with the present invention consists essentially in a push but toniitted in a casing which is embedded in the ioor, which push button moves vertically when pressed downwards with the foot. Alvhen this button is thus'pressed downwards, it causes a. lever to oscillate. To this lever is attached a 'cable which passes through pulleys and transmits movement to the actuating element of the water discharge apparatus. In case it becomes necessary to lengthen the range of movement given by the foot to the push button, suitable pulleys and multiplying gear are mounted upon the cable.

,In order that the invention ma be readily understood the sameis describe in connection with the accompanying drawings.

Fig. l, is a schematic elevation of the device as applied to a flushing apparatus havling an elevated water supply tank, ordinarily operated by hand.

Fig. 2, is a verticalk longitudinal section of the push button mechanism, and

Fig. 3, is a cross vertical section, of the same, Fig. 4, is a vertical longitudinal section of the multiplying gear, and

Fig. 5, is a front view of the multiplying gear.

Like references indicate similar parts throughout the drawings.

The example illustrated in Fig. 1, comprises the push button A, and the multiplying gear B; the latter is necessary in the present case, because the flushing device of the raised water tank type, such as C, is provided with an operating lever D, having a movement of a longer range than that of push button A. Fig. 1, illustrates the means of adjusting the different elements, namely, the push button A, is embedded in the floor, the button proper' only protruding. The cable operated by said push button passes through a pipe 1, embedded in the floor and which leads to the casing of the multiplying gear B. The latter is placed in an angle formed by the floor and the wall, and from there starts another pipe 2, which is yembedded in the wall and which rises to a level slightly lower than that of lever D. Cable 3, which passes through pipe 2, passes around a pulley 4, and then through a horizontal pipe 5, liXed to the wall; and lastly it passes through another pulley 6, liXed to the end of this pipe. Cable 8, is then attached to La stretcher Tf', hooked to lever D, of the dis-` charge apparatus. The object of this stretcher is to allow adjustment of the cable tension. I

Should the multiplying gear not be necessary, the cable leading from push button A, passes directly through guide pulleys to the water discharge apparatus. This requires no illustration.

Figs. 2 and 3, illustrate the push button in detail. It comprises a rectangular casing 8 open above, provided all around-with a horizontal flange 9, having a small vertical rib 10. This casing is embedded in the floor in such manner that yrib 10 is iiush therewith. In this casing is placed another casing vl1, also open above, and having flanges 12, which it exactly upon flanges 9 of the outer casing. A cover 13, having a central orifice for the push button proper I4, covers casing 11, and

vlits within rib 10, and is iXed, together with casing 11, upon casing 8, by means of screws 15. The lateral walls of casing 11, are provided with an orifice through which passes a horizontal transversal pin 16, which can r0- tate freely and is kept in a longitudinal position by the walls or' casing 8. Upon the center of this pin is mounted a lever 17, which can also rotate freely upon said pin but which is prevented from moving laterallyby means of a screw 18, the end of which entersa circular groove in the pin. One of the ends of said lever is in the shape of a cam and receives the pressure of rod 19, formed by a central lower projection of button 14:. The other end of lever 17, is provided with a cut in which is tied the end of cable A20., which operates the walter discharge apparatus,

cylinder flange 21, of cover` 13. This cylindrical part of the button is cut at its lower end #over a part ci its circumference to allow passage of pin 16, :and its .lower edge is provided with Aa 'lange 22, which limits the up- `wardmovement of the push button when the latter abuts against the loweredge of ythe cylindrical ,pant fof the cover..

Normally the push button protrudes above 'the loor a liew millimeters, being held in this position by the tension transmitted to the cable'by the flushing device. When pushing lsaid button with the foot, the :button causes lever 117 to loscillate, lever 1?? pulling on cable .20, which starts the water discharge apparatus. o

'Ua-sings -8 `and 11, are provided at one en-d 'with tan 4orilice through. which passes cable 20.. The .multiplying gear illustrated in Figs. 4: ando, comprises also a casing 23 whichis embedded im he angle formed by the iloor and the wall. This casing is open at the .front fand at its upper bac-k apart.; in .front itis provided at each side witha rib .24. This casing contains another casing 25, which is open .in iront, above amd below, :and which comprises .lateral tribs 2.6, for Vadjustment with the' ribs of the otherfcasin'g.. Theouter ycasing is highger than the inner one -suiciently to .allow the latter to be passed through the opening'of the fouter .casing existing .between the level iofithe :Hoor and the upper part. Said :inner lcasing is therefore placed in position by introducing rit insthorfizontal'ly and then vertically untill it 'rests .at the bottom fof the outer acasing.; when the inner casing .is .in position, the ribs are screwed together Aand the Lopening in the outer casi-ng is `closed by a screwed cover 27. -inner casing carries two horizontal 4cross pins 28, in the same manner as pin 1.6 in casing .11. Upon the lower pin rotates freely a pulley Q9, `upon which `coils cable `20, and

which is integral with a toothed Wheel lolli large diameter S30. The latter engages La fsmall pinion '31, integral with a large pulley 32, which iptates freely upon the upper pin. *0n Ithis pulley 32 is coiled cable 3, which leads to the flushing device proper. As will be readily understood, a short movement of `calole 20, produces a long movement of cable '3, which is the object of the multiplying gear.
